Frequently Asked Questions About Our Building Services in Bexley

Before starting a building project in Bexley, most homeowners have questions about planning, timescales, costs, and the type of work we carry out. Below are some of the most common queries we receive from customers across Bexley, Bexleyheath, Sidcup, and the surrounding areas — along with straightforward answers to help you move forward with confidence.

Do you cover all areas within Bexley?

Yes — we work across all parts of Bexley, including Bexleyheath, Sidcup, Albany Park, Barnehurst, and the wider borough. If you're unsure whether your property is within our coverage, just give us a call and we’ll be happy to confirm.

How much does a house extension or loft conversion cost in Bexley?

Costs vary depending on size, design, and structural requirements. Extensions in Bexley typically start from the tens of thousands, while loft conversions vary depending on the type (dormer, hip-to-gable, Velux, etc.). We provide free, detailed quotes with full transparency so there are no surprises along the way.

Do I need planning permission for building work in Bexley?

Some projects fall under permitted development, while others may require an application through Bexley Council — especially if you’re in a conservation area or altering the structure of your property. We can advise you during the consultation and help handle the entire planning process if needed.

How long will my project take?

Timelines differ by project type. Most single-storey extensions take around 8–12 weeks, loft conversions 6–10 weeks, and renovations vary depending on scope. After a site visit, we’ll provide a clear, realistic timeframe tailored to your property in Bexley.

Do you manage the whole project from start to finish?

Yes — we offer a complete design-to-build service, including architectural drawings, structural calculations, planning, construction, plumbing, electrics, and finishing. Everything is managed in-house, with one main point of contact throughout.

Can you work on older or period homes in Bexley?

Absolutely. Bexley has a mix of older homes, including Victorian and 1930s properties, and we have extensive experience renovating, extending, and improving them. We take great care to preserve character while upgrading structure, layout, and usability.

Will the project disrupt my day-to-day life?

We always aim to minimise disruption. Many clients stay in their homes during the work, and we maintain a tidy, safe, and organised site at all times. Clear communication ensures you always know what to expect.

How do we get started?

Simply contact us to arrange a friendly conversation or site visit. We’ll listen to your ideas, discuss options, outline costs, and guide you through the next steps — with no obligation and no pressure.
